Paris VideoPlan was commissioned by the RATP (Paris Metro)
to map the Madeleine district of Paris from the point-of-view of
walking down the sidewalk. It was filmed with a stop-frame 35mm
camera mounted on an electric cart, filming one frame every 2 meters.
An encoder was attached to one of the cart's axles. Rather than
filming all the turn possibilities at each intersection, a mime
was employed to stand in each intersection and simply point in the
possible turn directions. The idea was to substitute the perceptual
continuity of actual match-cuts with cinematic continuity. The playback
system was built in a kiosk and exhibited in the Madeleine Metro
Station
